gally sink question

[Chessie246G]

My Explorer has a gally sink (if you want to call it that). Electrical connection at the turn knob to turn on the pump. Currently its the only thing connected to the freshwater system. The issue Im running into is the water comes out like a 90yo man peeing, barely a trickle. Removing the hose from the fixture, water flies out full stream. (Connected to a Jasbco pressure pump rated to 30psi) I cant figure out how the fixture (or knob comes apart) Im sure something is corroded or partially blocked. The sink is molded into the gally area. Im guessing the electric switch under the flow knob is just a simple on/off rather that a resistor... But thats just a guess. I cant seem to figure out where the restriction is.

Typically not any electrical connections at the faucet. More likely a pressure switch that senses lower pressure when you open the faucet and turns on the pump, turning it off when you close it. Common problem is clogging of outlet usually has a screen inside at the end. Try unscrewing the tip of the faucet or if no screen, try unclogging from there.
